Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Führen mindestens eines Werkzeuges (10, 11) in bezug auf eine mittels Drähten (1) spalierte Kultur, wobei in einem als Führungsdraht ausgewählten Draht mittels eines sich periodisch ändernden Magnetfeldes ein Strom induziert wird, der ein sekundäres Magnetfeld um den Führungsdraht (1) herum erzeugt, das dann mit Hilfe von mindestens zwei auf gegenüberliegenden Seiten des Führungsdrahtes (1) befindlichen Magnetfeldsensoren (12, 13) gemessen wird, deren Meßwerte anschließend mit Hilfe einer elektronischen Steuereinrichtung (17) zu Steuersignalen weiterverarbeitet werden.The invention relates to a method and a device for guiding at least one Tool (10, 11) with respect to a culture trellised by means of wires (1), wherein in a wire selected as a guide wire by means of a periodically changing magnetic field a current is induced which creates a secondary magnetic field around the guide wire (1) generated around, which then with the help of at least two on opposite sides of the Guide wire (1) located magnetic field sensors (12, 13) is measured, the Measured values then with the aid of an electronic control device (17) for control signals to be processed further.

Um zu erreichen, daß das Werkzeug (10, 11) auf einfache Weise auch dann automatisch entlang eines als Führungsdraht ausgewählten Drahtes (1) nachführbar ist, wenn die Magnetfeldsensoren (12, 13) mit den Nutzsignalen Störsignale empfangen, die zwar eine größere Feldstärke, aber eine unterschiedliche Phase aufweisen als die Nutzsignale, schlägt die Erfindung vor, die Störsignale mit Hilfe eines phasenempfindlichen Gleichrichters (18, 19) aus dem empfangenen Signalgemisch herauszufiltern, indem ein mit dem Störsignal frequenzgleiches Referenzsignal, aber entsprechender Phasenverschiebung, dem Gleichrichter (18,19) zugeführt wird.

Figure 00000001
In order to ensure that the tool (10, 11) can also be automatically and easily tracked along a wire (1) selected as the guidewire when the magnetic field sensors (12, 13) receive interference signals with the useful signals, which indeed have a greater field strength, but have a different phase than the useful signals, the invention proposes to filter the interference signals out of the received signal mixture with the aid of a phase-sensitive rectifier (18, 19), in that the rectifier (18, 19 ) is supplied.
